Hydroxyethyl Cellulose muFracturing Fluid muOiri Kuchera

Hydroxyethyl cellulose (HEC) dzimwe nguva inoshandiswa mumvura inoputika inoshandiswa mukuchera mafuta, kunyanya mu hydraulic fracturing, inowanzozivikanwa se fracking. Fracturing fluid inopinzwa mugomba pakumanikidzwa kukuru kuti igadzire mafractures mumatombo maumbirwo, zvichibvumira kubviswa kwemafuta uye gasi. Heino nzira iyo HEC inogona kushandiswa sei mukuputika kwemvura:

1. Viscosity Modification: HEC inoshanda seye rheology modifier, inobatsira kudzora viscosity yeiyo fracturing fluid. Nekugadzirisa kusangana kweHEC, vashandisi vanogona kugadzirisa iyo viscosity kuti iwane inodiwa fracturing fluid zvivakwa, kuve nechokwadi chekufambisa kwemvura uye kusikwa kwekutsemuka.
2. Fluid Loss Control: HEC inogona kubatsira mukudzora kurasikirwa kwemvura mukuumbwa panguva yehydraulic fracturing. Inoumba keke yakaonda, isingapindiki sefa pamadziro ekutsemuka, kuderedza kurasikirwa kwemvura uye kudzivirira kukuvadzwa kwekuumbwa. Izvi zvinobatsira kuchengetedza kutendeka kwekutyoka uye kuve nechokwadi chekuita reservoir yakakwana.
3. Proppant Suspension: Mvura inoputika inowanzova nemishonga, yakadai sejecha kana zvidimbu zveceramic, izvo zvinotakurwa mumafractures kuti zvirambe zvakavhurika. HEC inobatsira kumisa mapuropu aya mukati memvura, kudzivirira kugadzirisa kwavo uye kuve nechokwadi chekugovera yunifomu mukati mekuputsika.
4. Fracture Cleanup: Mushure mekuita kwekutsemuka, HEC inogona kubatsira mukuchenesa iyo inoputika fluid kubva kutsime uye fracture network. Iyo viscosity uye yekurasikirwa kwemvura yekudzora zvivakwa zvinobatsira kuve nechokwadi chekuti mvura inoputika inogona kudzoserwa zvakanaka kubva mutsime, zvichibvumira kuti kugadzirwa kweoiri negesi kutange.
5. Kuenderana neZviwedzerwa: HEC inowirirana nemhando dzakasiyana-siyana dzekuwedzera dzinowanzo shandiswa mukuputika kwemvura, kusanganisira biocides, corrosion inhibitors, uye friction reducers. Kuenderana kwayo kunobvumira kugadzirwa kweakagadziridzwa fracturing zvinwiwa zvakagadzirirwa kune chaiwo mamiriro etsime uye zvinodiwa zvekugadzira.
6. Temperature Kugadzikana: HEC inoratidza kugadzikana kwakanaka kwekupisa, zvichiita kuti ive yakakodzera kushandiswa mukupwanya zvinwiwa zvakafumurwa kune tembiricha yakakwira downhole. Iyo inochengetedza rheological properties uye inobudirira sekuwedzera kwemvura pasi pemamiriro ezvinhu akanyanya, kuve nechokwadi chekushanda kwakafanana panguva ye hydraulic fracturing operations.

Hydroxyethyl cellulose (HEC) inogona kuita basa rakakosha mukugadzirwa kwemvura inotsemuka yemafuta ekuchera zvikumbiro. Kugadziriswa kwayo viscosity, kudzora kurasikirwa kwemvura, kumiswa kweproppant, kuenderana nezvinowedzerwa, kugadzikana kwekushisa, uye zvimwe zvivakwa zvinobatsira mukubudirira uye kubudirira kwehydraulic fracturing mashandiro. Nekudaro, zvakakosha kuti titarise iwo chaiwo maitiro emvura uye mamiriro etsime paunenge uchigadzira fracturing fluid formulations ine HEC.
